Torii Kiyonobu I was a Japanese painter and printmaker in the ukiyo-e style, who is renowned for his work on kabuki signboards and related materials. Along with his father Torii Kiyomoto, he is said to have been one of the founders of the Torii school of painting.
Known in childhood as Shōbei, young Kiyonobu was the second son of the established Osaka kabuki actor and painter Torii Kiyomoto, born in 1664. He moved, with his father, to Edo when he was twenty-four, and emerged there as a major artist with a unique style. Kiyonobu's work is regarded as being highly influenced by that of Hishikawa Moronobu, the father of ukiyo-e; Kiyonobu would also have been well-versed, as most major artists were at the time, in the styles of the Kanō and Tosa schools.
Kiyonobu focused almost exclusively on producing billboards and other promotional material for Edo's kabuki theaters; the relationship between the theaters and the Torii school was a strong and important one, and one that continues today. Guided by the need to attract attention, Kiyonobu's style tended towards bold, colorful exuberance.
